Tierra del Fuego Tree Ring Chronology from 288 BP

Tree ring data from Paso Garibaldi, Tierra del Fuego, Argentina provides a paleoclimate record spanning 323 years, from 288 to -35 calendar years before present. The NOAA National Centers for Environmental Information archives this dataset as part of its World Data Service for Paleoclimatology. The data was published in 1985.

Use Cases

• Reconstruct annual temperature or precipitation anomalies using tree ring width measurements.
• Calibrate regional climate models with proxy data from the Southern Hemisphere.
• Analyze climate event frequency, such as droughts or cold periods, over the recorded time span.
• Compare this chronology with other Southern Patagonian tree ring series to identify broader climate signals.

Strengths

• Data covers a specific 323-year period (288 to -35 BP) for climate reconstruction.
• Geographic location is precisely defined as Tierra del Fuego, Argentina.
• Archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1985, potentially lacking modern methodological refinements.
• Specific parameters, sample size, and measurement details are unknown without accessing metadata.
• Time coverage ends at -35 BP, limiting analysis of the most recent pre-industrial period.
